CLAMP, SURGICAL, GENERAL & PLASTIC SURGERY definition: A manual surgical instrument for general use is a nonpowered, hand-held, or hand-manipulated device, either reusable or disposable, intended to be used in various general surgical procedures. The device includes the applicator, clip applier, biopsy brush, manual dermabrasion brush, scrub brush, cannula, ligature carrier, chisel, clamp, contractor, curette, cutter, dissector, elevator, skin graft expander, file, forceps, gouge, instrument guide, needle guide, hammer, hemostat, amputation hook, ligature passing and knot-tying instrument, knife, blood lancet, mallet, disposable or reusable aspiration and injection needle, disposable or reusable suturing needle, osteotome, pliers, rasp, retainer, retractor, saw, scalpel blade, scalpel handle, one-piece scalpel, snare, spatula, stapler, disposable or reusable stripper, stylet, suturing apparatus for the stomach and intestine, measuring tape, and calipers. A surgical instrument that has specialized uses in a specific medical specialty is classified in separate regulations in Parts 868 through 892.
Clamps, Surgical definition: Clamps designed to compress anatomic structures and/or to bring together several isolated objects and/or tissue by pressing, fastening, or binding them firmly during surgical procedures. Surgical clamps are typically handheld, manual instruments including two parts pivoted at the center with blunt (i.e., atraumatic) distal ends. Dedicated surgical clamps are used for directly performing operative procedures directly or for holding ancillary devices in orthopedic, gastrointestinal, vascular, and other surgical procedures.

Clamps definition: Devices designed to compress a structure and/or to bring together several isolated objects and/or anatomic structures by pressing, fastening, or binding them firmly. Clamps are usually handheld, manual instruments with a working end that permits a large jaw opening and a handle and without a preferred resting state; dedicated clamps are available in a variety of shapes and sizes according to the procedure to be performed or the object to be held. Clamps are clinically used as dental, surgical, and postmortem instruments and/or to hold ancillary devices during those procedures; other clamps are intended to hold objects (e.g., test tubes, small instruments).
CLAMP, CANNULA definition: A blood access device and accessories is a device intended to provide access to a patient's blood for hemodialysis or other chronic uses. When used in hemodialysis, it is part of an artificial kidney system for the treatment of patients with renal failure or toxemic conditions and provides access to a patient's blood for hemodialysis. The device includes implanted blood access devices, nonimplanted blood access devices, and accessories for both the implanted and nonimplanted blood access devices. (1) The implanted blood access device consists of various flexible or rigid tubes, which are surgically implanted in appropriate blood vessels, may come through the skin, and are intended to remain in the body for 30 days or more. This generic type of device includes various shunts and connectors specifically designed to provide access to blood, such as the arteriovenous (A - V) shunt cannula and vessel tip. (2) The nonimplanted blood access device consists of various flexible or rigid tubes, such as catheters, cannulae or hollow needles, which are inserted into appropriate blood vessels or a vascular graft prosthesis (Secs. 870.3450 and 870.3460), and are intended to remain in the body for less than 30 days. This generic type of device includes fistula needles, the single needle dialysis set (coaxial flow needle), and the single needle dialysis set (alternating flow needle). (3) Accessories common to either type include the shunt adaptor, cannula clamp, shunt connector, shunt stabilizer, vessel dilator, disconnect forceps, shunt guard, crimp plier, tube plier, crimp ring, joint ring, fistula adaptor, and declotting tray (including contents).
Clamps, Cannula definition: Clamps designed for grasping and/or compressing a cannula without damaging it. These clamps are available in several sizes and configurations according to the cannula to be clamped and the procedure to be performed; they are frequently a flexible plastic mechanism that may be operated by a spring and attached to the cannula. Some cannula clamps are available as an integral part of a specialized device (e.g., a cannula attached to a hemodialysis fistula needle). Cannula clamps are used mainly in procedures (e.g., cardiopulmonary bypass surgery, hemodialysis procedures, oral surgery) that require a temporary closing of the cannula (i.e., the cannula is no longer patent).
CLAMP, CIRCUMCISION definition: An obstetric-gynecologic specialized manual instrument is one of a group of devices used during obstetric-gynecologic procedures to perform manipulative diagnostic and surgical functions (e.g., dilating, grasping, measuring, and scraping), where structural integrity is the chief criterion of device performance. This type of device consists of the following: (1) An amniotome is an instrument used to rupture the fetal membranes. (2) A circumcision clamp is an instrument used to compress the foreskin of the penis during circumcision of a male infant. (3) An umbilical clamp is an instrument used to compress the umbilical cord. (4) A uterine curette is an instrument used to scrape and remove material from the uterus. (5) A fixed-size cervical dilator is any of a series of bougies of various sizes used to dilate the cervical os by stretching the cervix. (6) A uterine elevator is an instrument inserted into the uterus used to lift and manipulate the uterus. (7) A gynecological surgical forceps is an instrument with two blades and handles used to pull, grasp, or compress during gynecological examination. (8) A cervical cone knife is a cutting instrument used to excise and remove tissue from the cervix. (9) A gynecological cerclage needle is a looplike instrument used to suture the cervix. (10) A hook-type contraceptive intrauterine device (IUD) remover is an instrument used to remove an IUD from the uterus. (11) A gynecological fibroid screw is an instrument used to hold onto a fibroid. (12) A uterine sound is an instrument used to determine the depth of the uterus by inserting it into the uterine cavity. (13) A cytological cervical spatula is a blunt instrument used to scrape and remove cytological material from the surface of the cervix or vagina. (14) A gynecological biopsy forceps is an instrument with two blades and handles used for gynecological biopsy procedures. (15) A uterine tenaculum is a hooklike instrument used to seize and hold the cervix or fundus. (16) An internal pelvimeter is an instrument used within the vagina to measure the diameter and capacity of the pelvis. (17) A nonmetal vaginal speculum is a nonmetal instrument used to expose the interior of the vagina. (18) A fiberoptic nonmetal vaginal speculum is a nonmetal instrument, with fiberoptic light, used to expose and illuminate the interior of the vagina.
Clamps, Surgical, Penis, Circumcision definition: Surgical clamps designed to to crush the inner and outer skin of the foreskin together to cause hemostasis during circumcision. These clamps are typically manual instruments that provide protection for the glans; usually, the foreskin is excised with a knife or scissors. Circumcision clamps are available in a variety of shapes and sizes, including reusable and single-use devices and adult and infant sizes.
CLAMP, PENILE definition: A urological clamp for males is a device used to close the urethra of a male to control urinary incontinence or to hold anesthetic or radiography contrast media in the urethra temporarily. It is an external clamp.
CLAMP, UMBILICAL definition: An obstetric-gynecologic specialized manual instrument is one of a group of devices used during obstetric-gynecologic procedures to perform manipulative diagnostic and surgical functions (e.g., dilating, grasping, measuring, and scraping), where structural integrity is the chief criterion of device performance.
